I used "plumbers putty" to replace the MISSING heat sink material on one of my 280c's. Later I did a test of my 280c with the standard factory heatsink foam material against my other 280c with the putty. Running the same program, same OS, same settings, the duo with the putty actually run a couple degrees F cooler. This is not a true scientific test. To be more scientific I would have switch the putty and foam from one machine to the other. Not gonna do it though! As another experiment, I cut two pieces of aluminum plate about an inch square each. Then squeezed a 1/8 inch thick layer of plumbers putty between them. Next heated one plate with a soldering iron. Results: the heat transfer from one plate to the other is not instant, but the second plate does eventually get too hot to touch. The putty does not go limp, but remains firm yet pliable even after cooling again. The putty I refer to comes in a small plastic tub and is used for, among other things, putting under the rim of a sink before you drop it into the hole in the kitchen counter top. It is much the consistency of Play-Doh. It should be noted that I tend to try things that are unconventional, and sometimes not necessarily wise!
